Buzzing sound from W555 engine

Hard to describe, but I have had a buzzing sound at the rear of my engine since purchasing the car years ago. Friends have reported that this is normal due to the design of the product, but I need to be sure of that fact before I am faced with a failure.

Would appreciate input from others who have had this experience.

Unfortunately your description is too general.

Could be anything, do you have a more narrowed down location, when does it happen, cold/warm/both, does it buzz when engine is off? The more info the better.
